So where are all of these music purchases coming from? Best Buy and Walmart, apparently -- both retail outlets saw their shares drop by a few percentage points recently. And of course these are all percentages. I'd bet that lower music sales overall combined with growing sales on iTunes is helping to grow Apple's share quite a bit. At any rate, while hardware sales are getting the press, let's not forget that iTunes is still a big earner for Apple.
